Happened every 20 seconds since the world came up. It says to report it to you guys and I am a rule following go-getter so I do like I'm told.

Running refinedstorage-1.2.3 with FML 2122

IMPORTANT UPDATE: Started up the server for a second time.. and no error message at all?

I'll update you guys on this one; its rather odd.

This issue happened immediately after upgrading to 1.2.3 but has NOT reappeared with any restart after. Reopen if there is something I've missed. Thanks guys.
